I'm looking for an online store that has boxer shorts, in stock, size
XL, for the following professional sports teams:

Atlanta Braves (baseball)
Chicago Bears (football)
New Orleans Saints (football)
Miami Dolphins (football)

I would prefer to be able to order them all from one online store, or
at most two online stores, as I need them express-shipped in time for
my uncle's birthday. (ie. the package(s) must be received no later than July 9)

The Braves and Dolphin boxers can be purchased at Yahoo store:

NFL: http://shop.store.yahoo.com/bestnflstore/nfl.html

The individual product pages for the boxers are:

Chicago Bears Boxer Shorts:
http://shop.store.yahoo.com/bestnflstore/chcc11.html

Miami Dolphin Boxer Shorts:
http://shop.store.yahoo.com/bestnflstore/mdcc11.html

If you want to check on the availability of Atlanta Braves and New
Orleans Saints, thus ordering from one store, you may try contacting
the company directly at:

E-mail: nflstorey@aol.com
Call Toll free 1-800-694-0060
Best Sports Apparel
206 Jack Nixon Dr Suite D
Fredericksburg, TX 78624

In any event, I'd call since you're order is a rush.

Atlanta Braves boxer shorts are available on the folowing page:

New Orleans Saints boxer shorts are another matter, and I can't tell
you why. I called the number on the Saints website for merchandise
ordering and they said they didn't make any. The lady I talked to
thought she saw some in the 5th Ave store last week. So I called that
number and the gentleman said they don't have them and doesn't think
anyone makes them. I've also scoured dozens of NFL apparel shop and
can't find a mention of Saints boxers. After searching as many
directories as I have, I can tell you with 80% assurance, that no one
makes them. That seems incredibly odd to me since they're available
for almost every other team I looked at.

Wish I could be more help on this latter. But hope this info helps!
Let me know if you have any thoughts on looking further or would like
me to look in a specific area.
